Description of key information

Additional information

This UVCB consists of complex inorganic boron, potassium and fluoride constituents, which are not biodegradable.

Methods used to determine persistence of organic chemicals are measures of the production of CO2, uptake of O2

, or reduction in dissolved or total organic carbon. Such methods are clearly not applicable to inorganic substances. Persistence/degradability has therefore limited or no meaning for inorganic substances according to the Organization for Economic Cooperation and Development (OECD, 2001). Rather the substance may be transformed by normal environmental processes to modify the availability of chemical species.
